Microsoft is investigating and working on addressing an ongoing outage affecting the company's Outlook webmail service.
According to information shared via the company's Microsoft 365 Status Twitter account, Redmond is performing targeted restarts to portions of the infrastructure impacted by a recent change.
The outage started at around 6 AM UTC on Tuesday and is affecting customers in North America and has spread out to other regions worldwide due to the affected infrastructure.
"Users in additional regions beyond North America may experience some residual impact due to the affected portions of infrastructure in North America," Microsoft says on its Office service health status page.
Microsoft also said in an update to its service health site that the current Outlook outage also affects additional functionality, such as the calendar consumed by other services like the Microsoft Teams communication platform.
Today's outage follows a major five-hour-long incident that impacted Azure and Microsoft 365 worldwide last week and took down multiple services, including Microsoft Teams, Exchange Online, and Outlook.
